Peptide manufacturers currently use peptides in cosmetics, which can be categorized into hydrolyzed proteins and functional peptides based on their source and efficacy. Hydrolyzed protein peptides are hydrolyzed products of animal and plant proteins, consisting of a multi-component mixture primarily composed of amino acids and containing a certain amount of oligopeptides.
They are mainly used for moisturizing and have no other special effects, such as hydrolyzed collagen peptides from animal skin and hydrolyzed oatmeal peptides from plants.
Functional peptides, also known as "beauty peptides" or "active bioactive peptides," are a class of small molecule compounds with specific amino acid sequences, simple structures, and clear mechanisms of action, with a molecular weight of less than 1000. Functional peptides possess high biological activity and biodiversity, primarily undergoing the synthesis and breakdown of proteins in organisms.
They can actively regulate the synthesis and secretion of proteins inside and outside cells, ensuring the expression and replication of genetic material, enhancing tissue and cellular metabolism, and thus regulating the body's growth, development, maturation, aging, and disease. Therefore, peptide manufacturers introduce the efficacy of functional peptides into the skin, including anti-wrinkle and anti-aging, repair, whitening and brightening, and allergy relief.
